Calendar slider - Shows only one competition

Hi i added SHORTCODE like this
[anwpfl-calendar-slider competition_id="628817,644472" filter_by_clubs="" group_by_competition="0" competition_country="" show_day_of_week="1" day_leading_zero="1" month_text="short" no_data_text="No games on this date" calendar_size="" competition_title="" centered="0" day_width=""]

Which was created with the shortcode builder. But calendar shows only games from the first competition_id not both.
